Asthma
Conditions
Brief summary
The primary objective of this study is to demonstrate the effectiveness of the Digital System (DS) in improving asthma control compared to the Standard of Care (SoC) group. The secondary objective is to describe the asthma management actions by investigational center health care providers (iHCPs) for all participants in both groups, to evaluate short-acting beta2 agonist (SABA) usage and the number of SABA-free days in the DS group, to evaluate adherence patterns to maintenance treatment (FS eMDPI) in the DS group, to assess behavioral correlates of responsiveness to digital health technology among participants for all participants in both groups, to evaluate work productivity and activity impairment in asthma participants in both groups, to assess the usability and acceptability of the DS by participants in the DS group and the investigational center personnel, and to evaluate the safety of FS eMDPI and Albuterol eMDPI.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants Achieving Well-Controlled Asthma or Reaching Clinically Important Improvement in Asthma Control | Week 24 | A well-controlled asthma was defined as an Asthma Control Test (ACT) score of greater than or equal to 20. Clinically important improvement in asthma control was defined by an increase of at least 3 ACT units from baseline. The ACT was a simple, participant-completed tool used for the assessment of overall asthma control. The ACT included 5 items that assessed daytime and nighttime asthma symptoms, use of reliever medication, and impact of asthma on daily functioning. Each item in the ACT was scored on a 5-point scale ranging from 1 (poor control of asthma) to 5 (well control of asthma), with summation of all items providing scores ranging from 5 to 25. The scores span the continuum of poor control of asthma (score of 5) to complete control of asthma (score of 25), with a cutoff score of 19 and below indicating participants with poorly controlled asthma. |

System Usability Scale (SUS) Overall Score for DS Group
The SUS was used to explore device acceptability and usability for participants in the DS group. It covered a variety of aspects of system usability, such as the need for support, training, and complexity, and thus giving a global view of subjective assessments of usability. It was a 10-question tool (with five response options; from 1=strongly disagree to 5=strongly agree) that provided a composite measure, ranging from 0 to 100, of the overall usability of the system being studied. Higher scores represent better usability level for the tool.
Time frame: Week 24
Population: The mITT analysis set all randomized participants who received at least 1 dose of IMP (IMP was either FS eMDPI or Albuterol eMDPI for the DS group or SoC medication for the SoC group) and at least 1 postbaseline ACT assessment. Here 'Overall number of participants analyzed' = participants evaluable for this outcome measure.
